E-workshop yaseJinbin, kuzothunyelwa iqoqo lama-valve e-butterfly aqinile avaliwe anezici ezintathu, ngobukhulu obusukela ku-DN65 kuya ku-DN400.ivalvu yebhabhathane engavamile kathathuiyivalvu yokuvala esebenza kahle kakhulu. Ngomklamo wayo oyingqayizivele wesakhiwo kanye nomgomo wokusebenza, ibambe isikhundla esibalulekile emikhakheni eminingi yezimboni. Isakhiwo sayo "esingavamile kathathu" siwuphawu oluyinhloko lomklamo: iivalvu yokuvala ibhabhathane eqinileI-axis yesiqu iyaphambuka kokubili phakathi kwepuleti lebhabhathane kanye naphakathi komzimba wevalvu, futhi ngesikhathi esifanayo, umugqa ophakathi wobuso obuyindilinga obuvalekayo une-engela ethile engafani nephakathi komugqa wepayipi.

Lo mklamo wesakhiwo wephula umthetho wokunyakaza kwamavalvu endabuko ebhabhathane. Lapho ivalvu ivulwa, ipuleti lebhabhathane kanye nesihlalo sevalvu kuyanqanyulwa ngokushesha. Ngesikhathi senqubo yokuvala, ipuleti lebhabhathane lisondela kancane kancane esihlalweni sevalvu, futhi ekugcineni lifinyelela ukuvalwa ngokucindezelwa okuhlangene kwamabhangqa okuvala anwebekayo noma ensimbi. Lesi sakhiwo sigwema ngempumelelo ukungqubuzana phakathi kwepuleti lebhabhathane nesihlalo sevalvu ngesikhathi senqubo yokuvula nokuvala, sandisa kakhulu impilo yenkonzo yebhangqa lokuvala, futhi ngesikhathi esifanayo sinciphisa i-torque yokusebenza, okwenza ukuvulwa nokuvalwa kwevalvu kube lula futhi kukhululeke.

Uma kuqhathaniswa nezinye izinhlobo zamavalvu, ivalvu ye-butterfly ye-Seal Butterfly eqinile ene-flanged inezinzuzo ezibalulekile. Okokuqala, inamandla okuvala kahle. Isakhiwo sensimbi esiqinile singafinyelela ukuvuza okungekho futhi simelane nokucindezeleka okuphezulu okufika ku-1.6MPa - 10MPa, sihlangabezana nezidingo zezimo zokusebenza ezahlukahlukene ezinomfutho ophezulu. Okwesibili, sinokumelana okuqinile kokuguguleka nokugqwala. Senziwe ngezinto ezikhethekile ze-alloy eqinile noma insimbi engagqwali futhi sisasebenza kahle ezindaweni ezinzima njengokushisa okuphezulu, umfutho ophezulu nokugqwala okunamandla. Okwesithathu, sinokuphila isikhathi eside kwenkonzo. Ngenxa yokuncipha kokuguguleka phakathi kwezingxenye, impilo yaso yenkonzo ingafinyelela eminyakeni engaphezu kwe-10 ngaphansi kwezimo zokusebenza ezijwayelekile, kunciphisa kakhulu izindleko zokulungisa. Okwesine, kulula ukuyisebenzisa futhi ingaqhutshwa ngezindlela ezahlukene njengokusebenzisa ngesandla, kagesi kanye ne-pneumatic, ihlangabezana nezidingo zokulawula okuzenzakalelayo ezimweni ezahlukene.

Ezisetshenzisweni ezisebenzayo, i-valve ye-butterfly eccentric kathathu evalekile eqinile isetshenziswa kabanzi ezimbonini eziningi. Emkhakheni wamakhemikhali kaphethroli, isetshenziselwa ukulawula ukuthuthwa kwezinto ezifana nophethroli, igesi yemvelo kanye nezinto zokusetshenziswa zamakhemikhali; Emkhakheni wamandla, ukugeleza kwezinto ezifana nomusi kanye namanzi okupholisa kungalungiswa ukuqinisekisa ukusebenza okuzinzile kwemishini yokukhiqiza ugesi. Emkhakheni wezinsimbi, isebenza ezinhlelweni zamapayipi zezinto ezifana negesi yesithando somlilo, umoya-mpilo, kanye ne-nitrogen. Emaphrojekthini okuphakelwa kwamanzi kanye nokukhipha amanzi, ivame ukusetshenziselwa ukusika amapayipi kanye nokulawula ukugeleza kwawo ezinhlelweni zokuphakelwa kwamanzi zasemadolobheni kanye nokwelashwa kwendle.

Ngokuphathelene nemidiya esebenzayo, ivalvu yebhabhathane e-eccentric yaseShayina ihambisana kahle. Ngokuphathelene nemidiya yegesi, ingasetshenziswa kugesi yemvelo, igesi yamalahle, umoya-mpilo, i-nitrogen, umusi, njll. Ngokuphathelene nemidiya ewuketshezi, ingaphatha uphethiloli, izixazululo zamakhemikhali, indle, amanzi olwandle, njll. Ngaphezu kwalokho, kwezinye imidiya exubile eqinile noma eqinile equkethe izinhlayiya nothuli, le valve ingaziphatha futhi ngokuzinzile, ibonise ukuzivumelanisa nezimo okuhle.
